bud explosion. the mc booster. it's super hot to run. mc alone should be enough for most folk.
i didn't say follow me exactly lol ...
i use starting about second wk of flower. the stuff can be touchy. it's not really charted in the MC nute sched. they give a suggestion online, it's far too hot to just add on top. i don't follow it at all lol.
we make head room by cutting back on the MC and literally feel it out judging by the plants.
i'd be hard pressed to be spending $20cdn / grow on media / RO / nutes. we're near $40 - $60 more with lighting etc .. so about $60 - $80 / grow right now. that's if i do long flower sativas ( ok - my faves ).
the power cost is rising though. and that is averaged through a few months.
our indoor grow season is kept to fall/winter/spring mostly.
